Abstract

Bimetallic particles based on gold and iron have been gathering increasing interest in biomedical applications because of the synergic combination of the plasmonic features of the inert gold component with the magnetic properties of the iron or iron oxide fraction, that makes these hybrid nanomaterials suitable for imaging, therapeutic and analytical applications. In this minireview, we emphasize gold-based nanomaterials with potential for Magnetic Resonance Imaging, focusing on Au-Fe hybrid systems as potential T-2-weighted, gold-based contrast agents.

Gold

Gold is a chemical element with the symbol Au () and atomic number 79. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental (native state), as nuggets or grains, in rocks, veins, and alluvial deposits.

Iron

Iron is a chemical element with the symbol Fe () and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, just ahead of oxygen (32.1% and 30.1%, respectively), forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust, being mainly deposited by meteorites in its metallic state, with its ores also being found there.

Oxidation state

In chemistry, the oxidation state, or oxidation number, is the hypothetical charge of an atom if all of its bonds to other atoms were fully ionic. It describes the degree of oxidation (loss of electrons) of an atom in a chemical compound. Conceptually, the oxidation state may be positive, negative or zero. While fully ionic bonds are not found in nature, many bonds exhibit strong ionicity, making oxidation state a useful predictor of charge. The oxidation state of an atom does not represent the "real" charge on that atom, or any other actual atomic property.
